vided with lateral projections which, by

adding weight to the jaws, reenforce the same and also, by riding upon the plates 22 at, the sides fof the opening 12, guide and support'the aws 1n their movements with a minimum frictional resistance and wear.

The wearplates'Qi are held by and bet-ween -thegfront bracket 19 and the rear bracket 22, the last-named; bracket also supporting terrupted' butpresents a smooth continuous surface against which the leather may be secured. I "per or fingerv is so shaped as to pass overthe rib or shoulder and the outer end of 'thefinger isturned down and plays in the the rear ends of the jaws. On their upper edges, the jaws are recessed "along their inner faces thereby providing a ledge 23 and a gage rib or shoulder Q24,=the upper 25 be-;

ing supported in the moldbyhaving its sole edge held "upon the ledge and against To retain the upper in the illustrated referring to'Fig.'5, it will be noted that'the slots or grooves do notextend through the shoulder so'that the said shoulder is not in- It will also be noted that the gripslot or groove,'a spring 28 being housed in each slot'or'groove between the shoulder and the fdownturned end of the finger and serving by itsexpansion to hold the front hooklike end of the finger in engagement with the edge of the upper, as shown in Fig. 5.

At their rear ends, the jaws or mold members are provided with tapered tongues 29 which are received within a slidable socket 30 and are normally pressed apart by a coiled spring 31 disposed between the inner face s ofthe jaws at the bases of the tongues and held in sockets formed therein as will be readily understood upon reference-to Fig. 3. The socket is carried by a fork 32 which is pivoted at its front end to the socket and i at its rear endis pivotally connected to the front end of a toggle link 33 and the upper end ofa pitman 34;, -the link being pivoted at its rear end to afbracket 35 on the table and 'thepitman being pivoted at its lower end to a foot lever or treadle 36' below the table. The treadle isfulcrumed upon a rod extending between the rear legsrl and its front end plays in a slotted guide 38 depending from the table, one wall of the 5 gui'ding slot being formed with stops or teeth 39 under anyone of which the treadle maybe engaged ,to be held inits .lowered position against the action of the spring 40 jwhich-is secured to the treadle and to the stantly upon release j hanger l and which raises fthe tr'eadle in of the same from the holding tooth 39.

In using the machine, an inverted upper is. suspended in the mold as shown in Fig. 9, the edge of the upper being stretched over the ledge 23 and againstthe shoulder 24. The last is then placed in position with in the upper and engaged over the pin or shank 11. The presser or plunger'9 is then brought down so as to force the last home upon the pin thereby stretching the upper closely upon the last. The treadle is then depressed, pulling downwardly through the pitrnan Maud straightening the toggle 33,

"32 whereby the socket 30 will be forced over the tapered tongues 29 and the jaws swung to the last so as to clamp and mold the upper against the last throughout the surface thereof. The treadle is then. engaged under a tooth 39. to be held depresseduntil the "shoe is to be removed, and it is to be noted that one of the jaws carries a leaf spring 41 receivable in av proper recess in the other aw sothat the joint between the jaws will be bridged and pinching of the upper as the mold is closed will be avoided. The presser or plunger is then raised and an insole 4:2

placed'upon the last to-lie flush with the outturned' flange of the'uppen'the insole and said flange being coated with cement. The outer sole 43 is then placed over the coated surfaces and the presse'r block brought down'upon the outersole, as shown in Fig. 10, so as to obliterate all blisters or wrinkles and obtain perfect contact and adhesion throughout the opposed surfaces:-

After the cement is dry the presse'r is raised, the fingers arewithdrawn from the upper, and the'treadle is released whereupon the socket 30 will be withdrawn from the tongues 29 and the mold opened. Bythen rotating the pin or shank 11 it will be caused to rise in its-bearing nut lO'and raise the last and the shoe thereonabove the mold to a point where they may be conveniently grasped and easily lifted from the pin. The pin is then lowered and the described operation repeated with another shoe. While the shoe is still upon the last the flange of the same is sewed or nailed to the outer sole and the edges of, the sole andthe flange't-rimmed smooth and even after which the last is removed from the shoe.

The method and mechanism so far described are for' producing a shoe with an outturned flange. To produce a shoe with an inturned flange, the mold previously described is removed and the'mold shown in 'Figs. 6, 7 and 8 is substituted therefor, the

substituted mold comprising a body 50 adapted to rest on the table between the brackets 19 and 22 and having a central opening 51, in which the upper is suspended. The opening 51 corresponds in shape to the shoe and {the last isarranged in the opening inthe same manner'as' previously described; Slidably mounted on thetop of the "mold are wipers, I pivotally mount an angle lever 53 on the mold adjacent each side wiper and one arm of the lever ispivoted to the adj a-' cent wiper while the other arm of the lever extends toward the adjacent side of the mold. The outwardly projecting arms of all the levers are pivoted to a link or push-bar 54: extending to the front of the mold andequipped with a handle 55 of any preferred or convenient form. One of the push bars is provided adjacent its front end with a lateral arm 56 extending toward the central plane of the mold and the free end of this lateral arm is connected by a link 57 with the toe wiper 52. At the opposite side of the mold, the push bar is pivoted at its rear end to a straight lever 58 which is fulcrumed between its ends upon the mold and has its inner end pivotally connected with the heel wiper 52. Gripper fingers 59 are provided upon the mold to stretch the upper and suspend it in the mold.

After the insole has been. placed in position, as abovestated, the gripper fingers are released and the push bars 5 f shoved rearwardly thereby actuating the wipers so that they will move inwardly over the edge of the insole and fold the edge of the upper onto the same. The outer sole, coated with cement on its under side, isthen placed over the insole and the inturned flange of the upper, after which the presser block is forced down upon the outer sole to hold the parts in contact until the cement sets, after which the shoe is removed and trimmed.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that I have provided a strong, compact, simple, and easily operated machine by which shoes, particularly those of the stitchdown type, may be rapidly lasted and the usual pulling-over machine dispensed with.

It is to be understood that I do not limit myself to the specific details herein described and shown as various minor changes may be made therein within the scope of the appended claims.

Having thus fully described my invention what I claimas new and desire to secure by Letters Patent of the United States is z- 1. The combination of a supporting frame, a mold mounted on the frame, means for suspending an inverted shoe upper in the mold, means for supporting a last, within the suspended shoe upper, and means for applying pressure to adhesive-coated insole and outer soles supported by the last with the edge of the outer side extending over the edge of the upper.

2. The combination of a supporting frame, a mold mounted thereon, means for supporting a last within the mold, gripper fingers mounted onthe mold to engage the edge of an upper and suspend the same between the last and the walls of the mold, and means for attaching a sole to the upper while it is suspended.

3. The combination of a. mold, slidable gripper-fingers mounted on the mold and having books at their inner ends to engage a shoe upper and suspend the same within the mold, and means coactingwith the outer ends of the fingers to retain them in upperengaging position.

4;. The combination of a mold provided with grooves in its upper side, the inner ends of the grooves being closed, gripper fingers extending over the closed inner ends of the grooves and having downturned outer ends playing in said grooves, shoe-upper-engaging hooks at the inner ends of the fingers, and springs housed in the grooves between the inner closed ends of the same and the downturnedouter ends of the fingers,

The combination of a mold provided with a ledge around the upper edges of its slde walls and a gaging rib marking the outerside of the ledge, grooves in the top.

gage the edge of a shoe upper and draw the I same overthe ledge and against the rib, and springs housed in the grooves and pressing outwardly ,against the downturned outer ends of the fingers.

6. The combination of a mold composed of opposed sections pivotally supported at their front ends, means for supporting a last between the sections, means on the sections to suspend a shoe upper between the last and the faces of the sections, and means acting on the rear ends of the sections to close them about the last.

7. The combination of opposed pivoted mold sections, tapered tongues projecting from the rear ends of the mold sections, a socket engaging over said tongues, means for moving the socket forwardly on the tongues CHARLES E. LOGAN.
